As a data point, I’ve been using asdf for a few months also. It works like a charm and would be great if I had to manage multiple versions.
I’ve only run into one minor issue. I sometimes use IntelliJ IDEA and it would not recognize asdf’s elixir or erlang installs as valid. I ended up symlinking ~/.asdf/shims/[iex,erl,mix] to /usr/local/bin which quieted IDEA down.
